Intel gigabit NIC issue.

Module loads fine however dhcp can't get an IP address and setting static IP doesn't work either. Could it be driver issue?

Define "doesn't work" -- how are you testing?

Configure a static address, then post the output of

ip a s
ip r s
cat /etc/resolv.conf
ping -n -c3 8.8.8.8
ping -n -c3 google.com

couldn't ping google.com because there is no dns configured. Also ping my default gateway 10.0.0.1 gave same result as pinging 8.8.8.8. I really think it's a NIC/driver issue.

Are you sure 10.0.0.0/24 is the correct subnet, and 10.0.0.1 is your gateway?

Can you `arping -I eno1 10.0.0.1`?

I see nothing that would suggest there is a driver issue -- Intel equipment is very well supported as far as drivers go, and there's no errors that point to hardware/drivers. Is there anything in dmesg to suggest there is an issue with drivers? The only "odd" thing I see is that you have 2 link-local (fe80::) addresses on eno1, which I've never seen before/can't explain.

ya everything is correct and i'll do arping when i boot into the archlinux install disk again.

here is my network information from windows:

You're doing this from the Installation CD, not an actual installation?

Have you tried using 10.0.0.3 instead of 10.0.0.180?

Yes I'm doing this on installation disk (usb drive) because I was told not to install archlinux without internet connection. And I haven't tried 10.0.0.3 i didn't think it would matter because I can use any ip from 10.0.0.2-254.

It shouldn't, but something isn't working. What kind of modem/router do you have? At a (wild) guess, if it has some kind of ARP issues, it might not be able to find your new address when it has a stale ARP entry for your mac address for example.

I actually have a windows server machine as my DHCP server, yesterday I deleted the ip lease from my dhcp server for that mac address and that didn't fix the issue either. So i doubt it's a arp issue but I will try that as my static ip when i reboot again into the installation disk.

fukawi2 · 2014-10-15 02:31:51

Is the Windows server your gateway/router as well?

Nope the windows server is just a dhcp server. My router is my gateway.

fukawi2 · 2014-10-15 02:47:51

OK, so your router could still have ARP issues or something potentially. A network diagram would be useful here.

here is a simple diagram im not sure if it's helpful

fukawi2 · 2014-10-15 03:03:54

OK, that's pretty much what I thought, but good to confirm

Let me know how you with the arping command.
